However, the complex synthesis process and the high synthesis cost of Spiro-OMeTAD severely limit the commercialization of this material. In this work, two economical methoxyaniline-substituted dibenzofuran derivatives, BF-002 and BF-003, are synthesized and successfully used as hole-transport materials in perovskite solar cells (PSCs). The important properties including light absorption, thermal stability
2,2',7,7'-四(N,N-二-对甲氧基苯胺)-9,9'-螺双芴(Spiro-OMeTAD)是一种经典的有机光电材料,已被广泛用作孔钙钛矿太阳能电池(PSC)中的传输材料(HTM)由于其相对较高的电导率,更容易的成膜,在可见光区域的吸收弱等原因,但是Spiro-OMeTAD的合成过程复杂且合成成本高,严重限制了这种材料的商业化。在这项工作中,两种经济的甲氧基苯胺取代的二苯并呋喃衍生物BF-002和BF-003是合成的,并成功地用作钙钛矿太阳能电池(PSC)中的空穴传输材料。系统地展示了重要的特性,包括光吸收,热稳定性,能级,电导率以及光伏性能。与基于Spiro-OMeTAD的PSC相比,基于BF-002和BF-003的PSC的最高功率转换效率分别为14.20%和14.07%。
